360 - mini hypnodisc

[Mouldy]

parcel finally arrived after ordering from RMP months ago with my new wheels…ended up having to track down jim on facebook and give him a poke to get them shipped… but… below are my new drive combos for 720 and 722;





Old school banebots kit in orange with my new motor support kits… in the grey is 722's new set-up, 2" wide colsons… still very grippy but harder wearing then the banebots stuff, if a bit more heavy…also the banebots gearbox has the optional longer shaft at the moment, which ill be cutting down slightly. The colsons being wider will have a nock on effect to 722's outer armour making it slightly wider then 720.

They look robust, can't wait to see the build of 722. Get busy!

That drive train looks very solid and reliable, although the 722 version must be getting close to 2 Kg for a pair with the heavier wheel.

[Mouldy]

Just checked... 1080g before chopping the shaft down... so 370g more than last year between the two drive setups... i was underweight this year but not by much... however im getting a smaller lipo so that should offset the difference a fair bit. I dont mind spending the extra weight if it proves more robust.... hopefully i can get enough weight for thicker top armour aswell... id like it to go upto 3mm grade 5 ti ideally... to achieve that the side armour will change a tad to save a few grams... will probably have a bit more ground clearance around the sides to allow it to flip over easier...and save a few grams lol

[overkill]

LOL, I wish I could guess the weight of my own parts that accurately. Estimating the weight of a new bot design is a thankless task - no matter how detailed I get, the real thing always weighs more! Are you going for Hardox or Ti side armour?

[Eventorizon]

722? Damn, as if the original wasn't dangerous enough!

I reckon it will be Hardox side armour. Will you be messing with the drum at all Dave? Going true single tooth or Making it wider etc...

[Mouldy]

Ideally hardox sides- where do you buy your titanium nick? I need some 3mm large enough for my top panel.

[calumco]

those motor support kits look good mate, a top geezer musta made those

[Mouldy]

Not much of an update but i found a weakness in the banebots during the champs, in that the circlip that holds the shaft in to the gearbox poped of twice on 2 different gearboxes, im putting this down to the amount of side movement in the shaft from new and the huge sideloading i put through them from not supporting the shaft on the opposite side...solved this by making up some spacers and tig welding the plate onto the shaft end after replacing the bearings with brand new ones as they felt a tad notchy.



Next proper update should be a bit better.

[overkill]

Nicely done! Your gearboxes are a newer model than mine, perhaps Banebots changed something that caused the circlip problem. The carrier plate looks a bit thicker, was it always that colour or is that caused be the TIG work?

[daveimi]

Always wondered if "just a circlip" as in the banebots pictures was a dodgy way of dealing with side ways loads.

[Mouldy]

The dimentions are exactly the same as the other style...im actually running the old style on the other side of the robot...as i had 3 old styles and had to order a new one and pressumed it would turn up the same

Also thats not the one which broke, that ones brand new...

The colour is just down to the welding- probably risidual machining oil on the carrier plate thats done it.

Hopefully it should work nicely. Im glad the side movement of the shaft has gone anyhow

[Mouldy]

Progress!



722's chassis on the left... few bits to do still including probably re making one bulkhead but you get the idea... thanks to andy at optipower for donating 6 awesome lipos for the robots! The smaller lipo means the tz85s can sit on the rear slide in plate and the lipo can go inside the rear bulkhead/back plate.

... previously the lipo and esc were very close to the top/bottom and were vunerable to axe attacks...

Also thanks obviously to ed for stamping me out another chassis from alumec 89 lol

Hopefully the carbon fibre for the electronics plates turn up soon so i can chop them out... then once im happy with the chassis i can start the armor.

[mrsam]

Is 722 getting a new drum or is the one from this year going on?

[daveimi]

Can see this being the one to beat. Be afraid, be very afraid, one of my plywood creations may be entering the champs next year muwahahahaha!!!
